Pop-up drain assembly

A drain stopper, comprising:

• a body and an elongated magnet, wherein
• the body has a length, a longitudinal axis, an upper end and an opposing lower end, wherein
• the body defines a circular cylindrical space that has an outermost cylindrical surface of the drain stopper, wherein
• the body has a magnet holder that has an outer surface that lies on the outermost cylindrical surface, wherein
• the magnet holder has a length that extends longitudinally along the outermost cylindrical surface, wherein
• the elongated magnet is received in the magnet holder, and wherein
• the magnet has a longitudinal axis that is radially offset from and generally parallel to the longitudinal axis of the body.

A drain stopper for a pop-up drain assembly, comprising:

• a central shaft having a length, a longitudinal axis and upper and lower ends;
• a fin A and a fin B that project radially from the shaft and extend along the length of the shaft for centralizing the drain stopper in a drain pipe;
• a cap on the upper end of the shaft;
• a magnet holder on fin B extending from away from the cap;
• and
• an elongated magnet having a longitudinal axis received in or on the magnet holder,
• wherein fin B has a radially outermost edge,
• wherein the magnet holder or the magnet has a radially outermost surface that is substantially aligned with the radially outermost edge of fin B, and
• wherein the longitudinal axis of the magnet is offset radially from and is substantially parallel to the longitudinal axis of the body.

A drain stopper for a sink or basin, comprising:

• a central, longitudinal shaft having a length, a longitudinal axis, an upper end and an opposing lower end;
• a cap received on the upper end for providing a seal to retain fluid in the sink or basin;
• first and second opposing plates for diverting flow away from the lower end of the shaft,
• wherein each of the plates has opposing upper and lower ends,
• wherein the upper end of each plate is fixed directly or indirectly to or is formed integral with the shaft,
• wherein the upper end of each plate is adjacent to or near the longitudinal axis,
• wherein the lower end of each of the first and second plates is spaced away from the longitudinal axis relative to the upper end of each of the first and second plates, respectively,
• wherein each of the plates has a planar surface, and
• wherein the planar surface of each of the plates is transverse to the longitudinal axis.

A drain stopper for a sink or basin, comprising:

• a central, longitudinal shaft having a length, a longitudinal axis, an upper end and an opposing lower end;
• a cap received on the upper end for providing a seal to retain fluid in the sink or basin;
• two or more fins that project radially from the shaft and that extend along the length of the shaft for centering the drain stopper in a drain pipe;
• first and second opposing plates for diverting flow away from the lower end of the shaft,
• wherein each of the plates has opposing upper and lower ends,
• wherein the upper end of each plate is fixed directly or indirectly to the shaft or to one of the fins or is formed integral with the shaft or with one of the fins,
• wherein the upper end of each plate is adjacent to or near the longitudinal axis,
• wherein the lower end of each of the first and second plates is spaced away from the longitudinal axis relative to the upper end of each of the first and second plates, respectively,
• wherein each of the fins and the plates have planar surfaces,
• wherein the planar surface of each of the plates is transverse to the longitudinal axis, and
• wherein the planar surfaces of each of the plates intersect the planar surfaces of each of the fins.
